  • Plesk 8.x for Linux/Unix

RESOLUTION

Plesk connects Parallels License Server (Key Administrator) at 5224 port for the license update procedure. Make sure that the outgoing connection to ka.parallels.com:5224 is not blocked on Plesk server or somewhere in the net. This can be examined with commands:

# nmap -P0 -p5224 ka.parallels.com
# telnet ka.parallels.com 5224
# traceroute ka.parallels.com

If you find that ka.parallels.com:5224 is not accessible from the server, try to stop firewall (iptables) and try to retrieve the key with the "Server > License Management > Retrieve Keys" button. If not, probably you should contact your ISP to open the port.
